I've managed to reproduce the problem. Choosing "read-write islands in
a read-only ocean" rather than "read-write document with some read-only
elements" cannot solve your problem. See below.

XXE's CSS engine does not automatically react to property changes like
it automatically reacts to attribute and/or child element changes. You
need to explicitly invoke DocumentView.rebuildView after you change a
``visual'' property of a node (I mean, which like property readOnly is
rendered in the CSS).
If you add this snippet at the end of your checkingDocument(), this
should solve your problem:
---
import com.xmlmind.xml.doc.DocumentListener;
import com.xmlmind.xmledit.view.DocumentView;
@Override
public void checkingDocument(Document doc, Reason reason,
URL saveAsURL) {
if (Reason.OPEN.equals(reason)) {
...
doc.endEdit();
DocumentListener[] docListeners =
doc.getDocumentListeners(true);
for (DocumentListener docListener : docListeners) {
if (docListener instanceof DocumentView) {
((DocumentView) docListener).rebuildView(doc);
brseak;
}
}
}
}
